A Bad Egg

A Bad EGG, named Bad Egg in Generation IV and Generation V, is an egg that one can obtain in all Generation III and on Pokémon games. Though the term is often also applied to glitched eggs in general, it is only used in-game to refer to noticeably-corrupt Eggs, which result from the use of cheat devices such as Action Replay, or Poké-GTS.

Generation II

It is possible to, through the use of a cheat device, catch an egg in the wild or turn a Pokémon the player already owns into an egg. Such eggs don't have any data specifying what they are supposed to hatch into, so the egg simply hatches into more eggs.

Sometimes, it is not possible to battle with a Bad EGG as its back sprite is undefined.

In these games, Bad EGG is called simply EGG.

Generation III

The Generation III games are the only games to actually make use of the term "Bad EGG". The string is used to identify eggs that appear to have been corrupted. The Trainer Memo section of such eggs' summaries invariably states that they are "A peculiar egg obtained in a trade." Such eggs do not actually hatch unless prompted by a cheat device.

The Elite Four in Generation III all have at least one Bad Egg in their party, when a cheat is utilized to capture their Pokémon.

Generation IV

In Generation IV, bad eggs are sometimes found by using a cheat to capture the opponent's Pokémon. Bad Eggs can also occur when the player uses a cheat device to catch Pokémon in the wild that are not found in the game, like Regice in Pokémon Pearl, or Mesprit in Pokémon SoulSilver. A normal Pokémon in the PC becomes identified as 'Bad Egg'.

Generation V

In Generation V, many glitches have been fixed that involves a Bad Egg such as that the game no longer freezes or corrupts. However, the Bad Egg cannot be removed if a cheating device is not used. The egg also cannot be used in a battle or be released. It acts like a normal egg that never hatches. If one manages to get one that hatches, the Bad Egg acts like an ordinary egg and freezes the game, a bug still remained unfixed.
